The metal'ingot is provided with teeth 4adapted to engage with a toothed wheel 5', Upon thefixed to the bar 9.This lever 11 has a fork 13' at one end, which supports a pin 14 passingthrough a float rod 15 carrying a float 16 suspended inside the metalpot. At the opposite end of the lever 11, there is a projection 17 whichisibrought-e-into engagement with: a fixed, --preferiennnmo; Manned-tattME'IlALzBITS 0FHEYP0GRAPH-ICAL ablygad justablaistop 518 whenythe metalpot is v 'moved, forward Eto :the :casting pos ition.

Moreover, the float 16 isalso'removable upwardly by reason of its loose suspension in the fork 13by the pin 14.

The inclination of the slots 20'for the bearings of the spindle 6 mustbe so Selected that, while the weight of the ingot3 will be adequate tosecurely hold the spindlel in its, operative position, the convenientraising of the spindle is permitted when the ingot is moved upwardly, bythe engagement of the teeth 4 with the pins 8.

The bearings 19 for thespindle 6'as well as the bearings 21 for the bar9 are made in one piece with the guide 2 and a plate 22, which can beconveniently connected tothe metal pot cover by screws or the like.
